Same Store Sales Explained

Same store sales method is a metric commonly used to evaluate the performance of already existing outlets by comparing the turnover generated in the current period to the turnover generated during the same period in the previous year, making the comparison fundamental and easy to understand.

The evaluation helps the company keep track of the unit having better performance and the unit with the weaker performance and thus plays a crucial role in the decision-making procedure for the management to focus on the more vulnerable areas and thus maintain the overall functionality and performance of the company.

Generally, the companies experience relatively positive growth in the total turnover generated by the company compared to last year’s figures. It happens typically because companies tend to increase their number of outlets and stores, which increases the company’s turnover.

For example, ABC Inc. is a manufacturing company with ten outlets throughout the state. The management wants to evaluate the performance of its two oldest outlets, ‘P’ & ‘Q,’ by evaluating the sales booked in February & March.

Following are the sales figures available for the outlets. Let us check the same store sales calculation and evaluate the performance of the outlets through the Same Store Sale method:



Let’s evaluate the performance of Outlet – P & Outlet – Q by using this method for both periods’ February’ & ‘March’ –

Performance of Outlet – P for the month of ‘February’ –

Same-Store Sales Example 1

Percentage changePercentage ChangePercentage Change can be defined as a % change in value due to changes in the old number and new number and the values can either increase or decrease and so the change can be a positive value (+) or a negative value (-). read more in Sales = ((20000 /18000) – 1) * 100 = 11.11 %

Performance of Outlet – Q for the month of ‘February’ –

Example 1.2

Percentage change in Sales =((22500 / 17500) – 1)*100= 28.57 %

Similarly, performance for March could be evaluated; and the result would be;

Performance of Outlet – P for the month of ‘March’ –

Same-Store Sales Example 1.3

Percentage change in Sales = ((17000/21000)-1)*100 = -19.05

Percentage change in Sales = – 19.05 % (negative since the sale volume decreased)

Performance of Outlet – Q for the month of ‘March’ –

Example 1.4

Percentage change in Sales =((17500/20000)-1)*100 = – 12.50 % (negative since the sale volume decreased)


This method utilizes the equivalent figures that are comparable to evaluate the percentage of change and the performance of a part, a store, or an outlet of an organization. In the above example, we can evaluate that the figures of the same outlet have been compared with the figures of the same period in both the fiscal yearsFiscal YearsFiscal Year (FY) is referred to as a period lasting for twelve months and is used for budgeting, account keeping and all the other financial reporting for industries. Some of the most commonly used Fiscal Years by businesses all over the world are: 1st January to 31st December, 1st April to 31st March, 1st July to 30th June and 1st October to 30th Septemberread more, which makes it more favorable an equivalent comparison. In case of comparison of figures for outlet P & Q for February, there is an 11.11% & 28.57 % increase in total sales of both the outlets respectively in the year 2020, whereas, in March, there is a decrease in total sales by 19.05% in case of Outlet P & 12.50% in case of Outlet Q. So this helps the organization to keep track of its total performance regarding sales and identify its strong point and weak areas at the same time.
